Hello,

I was wondering if there were any ways to secure gears on shafts. I don't mean along the axis of rotation (that is easily solved by hex/keyway broaching gears or carefully welding). How would I keep a gear from sliding along a hex shaft if it was already broached to the correct size?

I have thought of tack welding, roll pins, spacers, and set screws in the place of roll pins.

I ruled out tack welding because it would be nice to be able to reuse the gears in a case of emergency, and I don't have the clearance in some parts for spacers.

I am probably going to resort to using set screws but I was wondering how some other teams secured their gears on shafts.

thank you, Vivek
